Specification of Letters Patent.

Patented Jan. 31, 1911.

Application filed october 21, 1910. Serial No. 588,316.

To all whom t may concern:

Be it known that l, Monrrz LonwnNs'rniN, a citizen ot the United States ot american and resident of St. Louis, Missouri, have invented certain new and useful mprovements in Tobacco-Pipes, of which the following is a specification containing a i'ull, clear, and exact description, reference being had to the accompanying drawings, torming a part hereof.

My invention relates to improvements in tobacco pipes, with .special reference to a reversible bowl, a drain and a cheap and easily 'removable and replaced absorbent, thus producing a pipe practically sanitary.

For the above purposes, my invention consists in certain novel features of construction and arrangement ot parts which will he hereinafter more tally set forth, pointed out in the claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a sectional disassembled view; F ig. 2 is a sectional assembled view ot the complete pipe; and Fig. 3 is a plan oi the self-adjusting disk which holds the absorbent material.

Referring by numerals to the accompanying drawings: 1 indicates the base or lower bowl oi the pipe. Said lower bowl has a pipe stem opening Q and a metal errule 3, Formed in the base or lower bowl is an annular depression 1. Terminating in a circular groove 5 and arising within the depression L1 is a conical elevation 6, in which is formed a screw-threaded depression 7. Formed on the upper part et the base or lower bowl 1 is an annular flange S. This flange 8 is larger in its internal diameter than the depression 1, thus toi-ming an annular shoulder' 9. Leading trom the groove 5 to the pipe stem opening 2 is a smoke opening 10. The said smoke opening 10 terminates at its upper end at the upper portion or side of the pipe stem opening 11 indicates a pipe stem provided with the usual smoke opening 12, the lower end otl which projects below the upper end ot the smoke opening 10. Below the pipe stem opening 2 is a depression 13, which acts to receive some ot the saliva and condensation ot the smoke.

14 indicates a reversible bowl, the opening of which is of uniform diameter throughout,

and is adapted to be seated within the flange S.

Located within the depression 4 and on top of the conical elevation G is a body of absorbent material 15. This absorbent material is held in place by a conical disk 1G, in the center of which is formed a depression and an opening 17 and perforations 18. A segment of the disk is cut away at 19, thus permitting the disk to be reduced in diameter or its top surface and its edge contracted. This convex disk is held in place by means oi a screw 20. Vhen this disk is secured within the lower bowl or base 1, an annular cavity or opening 21 is formed between it and the inside of the iange S in which the lower edge of the reversible bowl 141 is seated. Then the pipe has been smoked tor some time and the reversible bowl la is thoroughly dried it shrinks somewhat, and its internal diameter becomes somewhat smaller, and in order for it to be properly seated within the lower bowl 1, it is necessary for the convex disk 16 to be capable et contracting. Then the convex disk 16 is applied within the lower bowl its edge rests on the shoulder 9. The conical elevation 6 not only forms a reinforcement around the screw-threaded depression 7, but it tends to spread the absorbent material, such as cotton, against the sides of the de pression 4t and in the groove Should any saliva or 'fluid gather in the groove 5, it can be readily drained out through the smoke opening 10.

1n the above construction it is apparent that smoke from the tobacco will pass through the opening 19 and pertorations S ot' the disk 16, through the body of absorbent material 15, the smoke opening 10, and finally, out through the smoke opening 12 of the stem 11.

lWhen the absorbent material 15 has absorbed the objectionable -iiuid incident to smoking, it may be removed and a fresh sup ply inserted. In practice I use as the absorbent material ordinary cotton, which is very cheap, and it need not be prepared in any special form, as the convex disk 16 and conical elevation 6 conforms the cotton. It is also apparent from the construction herein described that the reversible bowl 14: is practically held in place not only by the flange 8, but by the top surface of the yielding disk Y1G, and as the internal diameter' of the bowl let contracts by use, the opening 19 in the disk 16 will permit the bowl to be properly seated at all times.

I claim:

l. In a tobacco pipe, the combination of a lower bowl having an annular depression formed therein terminating in an annular groove and a conical elevation arising within the groove, the said conical elevation being provided with a screw seat, the said bowl being provided with an annular flange, a contractible convex disk located in said bowl and a screw for securing said disk in position, a body of absorbent material positioned in the bowl beneath said disk, and a reversible bowl adapted to be seated within the flange and the contractible disk.

2. A tobacco pipe comprising a lower bowl having an annular depression, a groove, a shoulder and a ilange, a contractible conveX disk seated on said shoulder, a screw for holding the same in place, a body of absorbent niaterial positioned around the screw and beneath the disk, the said lower bowl being provided with a smoke opening leading into said groove, a stem opening and a stem seated in said opening, and a reversible bowl seated in the flange and between the said flange and said convex disk.

3. In a tobacco pipe provided with a reversible bowl, a lower bowl provided with a flange, shoulder and an annular depression and groove, a convex contractible disk seated on said shoulder, a body of absorbent material located beneath the disk, and a screw for holding said disk in place.

In testimony whereof, I have signed my name to this speciiication, in presence of two subscribing witnesses.
